With a fractional PRI of 8 Channels, is it possible to dedicate 4 channels for Incoming only and 4 channels for outgoing only.

The Voice Gateway used would be 3845, with IOS version 12.4.

Can this be achieved using CUCM v7.

On E1R2 signaling, you need to configure 2 ds0-groups on the controller E1. By doing this, you will have 2 voice ports. Use one for inbound calls and the other one for outbound calls by matching numbers on the destination pattern and associate that call with the outbound voice port number.

Also, can we have 4 Channels dedicated for 4 IP Phones only, such that no other overflow call comes on these 4 channels.
